Abstract

The invention provides a remote upgrading system and method based on an FPGA and a medium. The system comprises an upper computer, the FPGA and a FLASH chip. The method comprises the steps that an upper computer selects a BIN file to be upgraded, issues a handshake frame and waits for an FPGA to reply an acknowledgement frame; after receiving the FPGA handshake acknowledgement frame, the upper computer sends an erasure frame; when the FPGA executes the command to successfully erase the FLASH, an erasing success confirmation frame is replied to the upper computer, and the upper computer starts to issue a data frame to be upgraded; the FPGA writes the data into the FLASH; and after all data to be upgraded are written into the FLASH, the FPGA reports an acknowledgement frame to the upper computer, and the upgrade is finished. According to the invention, the FPGA program is updated more simply and conveniently, the PCB circuit design is more optimized, the updating rate of the FPGA is improved, and the remote updating of the FPGA becomes safe and reliable.

Description

technical field [0001] The present invention relates to the technical field of embedded systems, in particular to an FPGA-based remote upgrade system, method and medium. Background technique [0002] Programmable logic device FPGA devices have the advantages of high density, low power consumption, high speed, high reliability, etc., and have been widely used in aerospace, communication, industrial control, etc. Since the FPGA device uses an SRAM process, the configuration data in the FPGA will be lost when the power is turned off. Usually, the FPGA is connected to an external Flash to store configuration information. After the system is powered on, the FPGA automatically reads these files to complete the startup. [0003] At present, there are mainly three kinds of FPGA upgrade schemes: 1. Use the JTAG interface to upgrade the FPGA. This method is suitable for use in the product debugging stage. When the product is put into actual use, the update of the FPGA program require...
